These figures were in display cases at E3 2014. The Eggman here appears to be the same as the one in the Egg o Matic above (could it be a set?) The Tails & Knuckles are different from their prototype forms seen on the Proto Page.

But look who's here! The fan-favorite wacky badniks: Orbot & Cubot! And they have not been inexplicably changed for Boom! So even if you don't want "Boom style" you can still enjoy poseable figure Orbot & Cubot here. Knuckles has been given his red "lightening magic string" seen in the game demo (running in the background) that the characters use to grapple and grab enemies. Tails' accessory details seem good, as does his face sculpt. 

There is also the E3 shot of the robot figure but look there beside it...it's Sticks the badger! With her in there for scale, you can see that the robot here is actually really huge. It also shows you how it will stand, you have to use the arms & the legs to keep it standing since it does not particularly have feet.
